To all whom it may concern:

Be it known that we, ROBERT S. FRARY and WALTER W. MACFARREN, citizensof the United States, residin at Pittsburgh, in the county of Allegheny,btate of Pennsylvania, have invented certain new and useful Improvementsin Sash-Holders, of which the following is a specification.

Our invention relates to sash holders for Referring to the drawings;Figure 1 is a vertical section through a portion of a window frame andits associated sash showing side elevation of our improved sash holderin operative position. elevation of the spring. Fig. 3 is an endelevation of the fluted roller. Fig. 4 is a side elevation of the same.Fig. 5 is aside elevation of the pawl. Fig. 6 is an end elevation of thesame. Fig. 7 is a side elevation of a portion of the spring showing amodified form of lug attached thereto. And Fig. 8 is a cross sectionthrough the spring and its lugs showing the method of inserting theroller.

The window frame 1 is provided with a thin working strip 2, preferablymade of vulcanized fiber or similar non-metallic material which is notaffected by the weather.

The sash 3 is provided with a recess 4, this recess being somewhat lessthan the thickness of the sash as will be readily understood, and withinthis recess we mount our improved sash holder, which consists of threemain elements, a bowed spring 5, a fluted roller 6, and a pivoted pawl7. The

7 spring 5 may be stamped from sheet steel of proper quality, and may beof uniform thickness throughout, or it may be of tapering section, beingthicker in the middle.

The spring 5 is provided with a flange 8 at its upper end which abutsagainst the upper surface 9 of the recess 4. At the upper end of thespring just below the flange 8 a hole 10 is formed, and at the lower endof the spring there is an elongated hole or slot 11. Screws 12 and 13fasten the spring to the sash. A pair of lugs 14 are formed on themiddle portion of the spring and are preferably integral therewith. Each111g 14.

Fig. 2 is ans is provided with an upper hole 15 and a lower hole 16,these holes being opposite each other in the adjacent lugs.

The roller 6 is provided with integral journals 17 for which the holes16 form bearings. The pawl 7 is provided with similar journals 18, forwhich the holes 15 form bearings.

In the manufacture of, the spring 5 one of the lugs 1 15* is bent to aright angle with the body of the spring, and the opposite lug 14 is bentto such a position that the journal 17 of the roller 6 can be insertedin the hole 16 before the finishing bend is given to the lug 14 Thejournals 18 of the pawl 7 are engaged bythe holes 15 at the same time.

The roller 6 is provided with fluted or grooved surface as shown at 19.These grooves are formed with a radial side 20 and a curved portion 21which connects with the cylindrical surface 22 of the roller. As flutes22 are comparatively small and few in number the smooth actionof theroller is not interfered with. It will be noted by reference to Fig. 1that the parts are so assembled that one of the portions 22 of thecylindrical surface of the roller bears against the working strip 2 whenthe pawl 7 engages one of the flutes 19 so that the sash can be moveddownwardly without any scraping action being produced by the roller 6 onthe working strip 2.

In Fig. 7 we have shown a portion of the spring 5 and a modified form oflug 23, there being two of these held together by a connecting piece 21, the same being connected to the spring 5 by rivets 25. lVhile thisconstruction serves the same purpose as the one shown in Fig. 1, it ismore expensive to make and only of advantage when very heavy springs areto be employed. In Fig. 2 we have shown in dotted lines the outline ofthe lugs 14: as they are punched from the sheet before being bent. Itwill be observed that by forming the lugs 14: integrally with thesprings 5, and by forming integral journals on the roller 6 and the pawl7 that the entire device with. the exception of the fastening screws iscomposed of only three parts, and is so assembled that the parts cannotunder ordinary circumstances become detachedor alter their relation witheach other.

The use of a fiber working strip insures a uniform smooth track, havinga surface well adapted for the frictional engagement of the roller inthat it has a high co-eflioient 7 spring adapted to be secured to thesash in a recessed portion thereof, lugs carried by said spring, twosets of holes insaid lugs,

a fluted roller provided with integral journals engaging one set ofholes, and a pawl also provided with integral journals engaging theother set of holes. I

2. A sash holder comprising a bowed spring adapted to be secured tothesash in a recessed portion thereof, lugs formed integral with saidspring and projecting therefrom, a fluted roller carried by said lugs,and a pivoted pawl also carried by said lugs and engaging said roller.

3. A sash holder comprising a bowed springadapted to be secured-to thesash in a recessed portion thereof, a roller carried by said spring forengaging the. window frame, a pawl carried by said spring to preventrotation of the roller in one direction, anda flange formed on the upperend of said spring to abut against the upper surface of the recess inthe sash. I

4. A sash holder comprising v a bowed spring adapted to be secured tothe sash in a recessed portion thereof, outwardly and upwardly extendinglugs carried by said spring, and a roller and a pawl carried by saidlugs. I

5. A sash holder comprisingithree members, viz., a roller, a pawland aspring, said roller and saidpawl being mounted on said spring, and meansfor securingthe device to a wlndow sjash.

In testimony whereof we hereunto affix our signatures in the presence,of two wit-j nesses.
